The following are m y notes of the dissection of the viscera:- On opening the abdomen the mesentery is seen moderately covered with fat; but the large stomach, which is full of food, occupies the chief part of the abdominal space. The length of the intestinal canal, which is not furnished with a caecum, is as follows:- ft. in. Oesophagus 2 10 Stomachs . 5 10 Small intestines 99 8 Large intestines 10 2 Total 118 6 The commencement of the large intestines is indicated by a sudden enlargement of the tube, and by the gland to be hereafter noticed. The stomach (fig. 3, p. 604) has a very peculiar form, and differs materially from that of any other pachyderm, indeed from that of any other animal. The oesophagus (A), the lining membrane of which is smooth, but arranged in slight longitudinal folds, terminates between the first and second stomachs (B, C ) . These cavities are of about equal size, of a somewhat cylindrical form when distended. The right cavity (B) measures 19 inches in length and 6 at its widest part; it will contain about three quarts of water. The left cavity (C) is 21 inches in length and 4\\ at its widest part; in capacity it is about the same as the last, as it is thinner and more distensible. Proceeding from between these cavities is the third stomach (D), of a cylindrical form, 20 inches in length and 5 at its widest part; it holds about three quarts. The fourth and last stomach (E) is of a rounded form, 14 inches in length and 10 at its widest part; its capacity is about six quarts. The interior of these viscera present a remarkable appearance. The oesophagus (A) appears to enter equally into both the first cavities ; but in the right cavity is a strong muscular slip (1) of a somewhat crescentic shape, extending for about 6 inches along its upper part, the object of which appears to be to direct the food into the left stomach ; but other observers may take a different view of this question. The left cavity is furnished with about sixty-five longitudinal rows of detached papillee of a rounded form, elevated about a line above the surface, giving somewhat the appearance of |
